Pennsylvania will require advertisers to explicitly label any commercial content generated or substantially modified by artificial intelligence starting December 21, 2026, positioning the state among the first in the U.S. to enforce such disclosure rules.
Josh Shapiro signed the Artificial Intelligence Deceptive Advertising Act, designated as Senate Bill 806 or Act 99 of 2026, on October 22, 2026. The legislation cleared the state House of Representatives on October 7 with a 163 to 40 vote. The new mandate applies to digital and traditional media alike, requiring clear and conspicuous labels whenever synthetic media creates a false consumer impression regarding the origin or authenticity of goods and services.
The statute gives commercial entities exactly 60 days from its enactment to overhaul their marketing workflows. Ad formats containing text, audio, images, or video significantly altered by AI must carry durable, hard-to-remove disclosures. The mandate covers any campaign targeting Pennsylvania residents, regardless of whether the creative assets originated inside or outside the commonwealth.
Yet, the statutory definitions leave room for interpretation. Legal analysts at Loeb & Loeb observed that the text lacks precise thresholds for what constitutes a “significant modification” or an “obvious fiction.” Furthermore, the legislation explicitly exempts satirical content, parodies, reviews, critiques, and plain text from the labeling requirement.
Unlike regulatory models emerging elsewhere in the country, Pennsylvania lawmakers stripped a provision requiring proof of willful intent or negligence before penalties attach. Enforcement rests exclusively with the state Attorney General and 67 district attorneys, shutting out private rights of action. Violators face civil penalties of up to 3,000 US-Dollar per infraction, alongside court and attorney fees.

This commercial rule moves independently from parallel legislative efforts targeting elections. House Bill 811—a separate proposal to penalize unlabeled AI in political campaign advertising with civil fines reaching 50,000 US-Dollar—remains blocked in the state Senate. Meanwhile, local jurisdictions are carving out their own paths, with the Allegheny County Council passing a local ordinance requiring candidates to flag AI content starting in January.
| Jurisdiction | Legislation Name | Effective Date | Penalty Range (USD) |
|---|---|---|---|
| California | AB 2602 | January 1, 2025 | Varies by labor code remedies |
| New York | Synthetic Performer Law | June 9, 2026 | $1,000 – $5,000 per violation |
| Pennsylvania | Act 99 of 2026 (SB 806) | December 21, 2026 | Up to $3,000 per violation plus fees |
As the December deadline approaches, small businesses and national agencies launching campaigns into the region must evaluate their compliance frameworks. Senator Nick Pisciottano’s office has not released further guidance on how prosecutors will interpret the law's vaguer provisions, leaving legal teams to manage the transition ahead of the winter enforcement date.
